Din | 5480 Pdf

DIN 5480 is a fundamental German engineering standard for involute splined connections based on reference diameters. It is widely considered an "interesting piece" because it revolutionized how spline geometry is calculated, moving away from older pitch-based systems to a more streamlined diameter-based approach. Key Highlights of DIN 5480

The scope of DIN 5480 includes:

• Quality class A: The highest quality class, with the tightest tolerances.
• Quality class B: A medium-quality class, with less stringent tolerances than quality class A.
• Quality class C: A lower-quality class, with less stringent tolerances than quality class B.
• Quality class D: The lowest quality class, with the least stringent tolerances.

• Current version: 2006 (Parts 1 and 2 were consolidated and revised in March 2006).
• Supersedes: All versions from 1991 and earlier.

For CNC Machining (Hobbing or Shaping):

• The tolerance tables (found in DIN 5480-2) are non-negotiable.
• For an external shaft (male spline), common tolerance is 8f.
• For an internal hub (female spline), common tolerance is 7H.
• Always cross-reference the "ball diameter" measurement from the PDF to program your CNC gear checker.
